IMPROVEMENT IN CO AL-OlL STOVES.

Specification forming part of Letters Patent No. 156, I49, dated October20, 1874; application filed July 8, 1874.

To all whom it may concern Be it known that I, JOHN A. FREY, ofWashington, in the county of Washington and in the District of Columbia,have invented certain new and useful Improvements in GoalOil Stoves; anddo hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingsmaking a part of this specification, in which- Figure l is a perspectiveview of my stove as arranged for use. Fig. 2 is a like view of the samewith the upper hinged portion turned to one side so as to uncover thewick-tubes, and Fig. 3 is a vertical central section upon a line havinga right angle to said tubes.

Letters of like name and kind refer to like parts in each of thefigures.

My invention is-an improvement upon a similar device which has beforebeen manufactured and sold by me, and which is protected by severalpatents; and it consists in the peculiar construction of the funnel orchimney, and its combination with the wicktubes, substantially as andfor the purpose hereinafter shown.

In the annexed drawings, A represents the reservoir for containing oil,which reservoir has, preferably, downward and outward flaring sides, andat its upper side and outer edge is inclosed by means of an annularflange, B, that has a height of about one and one-half inch, and is usedto contain water for receiving the heat radiated downward from theburners, so as to prevent the same from being communicated to the oil.From the reservoir A two tubes, 0 and G, extend upward to the requireddistance, and serve to contain wicks 1) and D, of usual shape. Saidwicks are moved vertically by means of starwheels E and E, which latterare secured upon, and rotate with, suitable shafts, e and e. In orderthat the wick-wheel shafts e and 0 may be prevented from becoming warpedby the action of the heat, so as thereby to change the relativepositions of the wicks and engaging wheel, said parts are located withina suitable housing, 0, below the waterline, by which means a perfectprotection is afforded, and all liability to derangement avoided. Aboveand around the upper ends of the wick-tubes G and G is placed a cap, F,that is provided with cone-shaped kerbs f and f, one of which coincideswith each of said tubes,and permits the flame of the burning oil to passupward from the wick. From the cap F, which is, preferably, constructedfrom cast metal, a sheet-metal cylinder, G, extends upward about seveninches, and at its upper end is inclosed by a metal head, H, whichlatter is provided with two openings, h and it, that coincide inposition with the wick-tube kerbs f and f, but have considerably largerhorizontal dimensions. From each side of each opening h a flange, It,extends downward, and causes the heated escaping gases to be deflectedtoward the ends of said openings, instead, as would otherwise be thecase, of passing outward, principally at the longitudinal center of thesame. The cyliir der G, cap F, and head H, which form the chimney of thelamp, are hinged so as to permit of being turned to one side, as shownin Fig. 2. An elevated support, I, for cooking utensils, is secured tothe upper end of said cylinder, and a number of glazed openings, K andK, are provided in the sides of the latter, completing the apparatus,the operation of which will be readily understood from the foregoingdescription.

Having thus fully set forth the nature and merits of my invention, whatI claim as new The combined cap and chimney, consisting of the cap F,provided with the kerbs f and f, the sheet-metal cylinder G, and thehead H, provided with the openings h and h, and flanges or flue-plates hand h, depending from the sides only of said openings, said parts beingconstructed and combined to operate in the manner and for the purposesubstantially as shown.

In testimony that I claim the foregoing I have hereunto set my hand this26th day of June, 1874.

JOHN A. FREY.
